' YsiLo (ATTACHMENT.

Be it known that I, LESTER E.y OHMART, a citizen of theV United States, residing at Hope, in the county of Dickinson and State ofL Kansas, have invented certain new and -useful Improvements'in Silo Attachments,

of whic-h the following is a specification.

My invention relates to devices for facilitating the lifting into' place of the blower pipeyhood andv other connections whereby the ensilage is conveyed from,x the cutter on the ground, over the top, and' into the interior of the siloand as well to the means for holding the upper end of the conveyer and its attachments while -in operation.-

Theobject is to produce a simple, cheaply made, strong, durable, light, portable and adjustable device to facilitate the lifting of the conveyer from the ground to the top; also to provide in connection therewith a means for lifting the distributerpipe inside l the silo; also to provide in connection therewith a suitable means for securely anchoring` the upper end of the conveyer to the silo wall. The invention comprises a frame which Ais a made so as to be adjustable to any width of silo wall and formed with a pair of out wardly projectingk spaced arms, together with a pulley removably supported between the arms; it also comprises in connection therewith, a second pair of spaced arms with a pulleyv above the interior of the silo for lifting the distributer; it also comprises certain parts, improvements and combina.-

rtions relating thereto as hereinafter set forth Aand claimed.

In the drawingsforming a part of and accompanying this specification, I have shown my invention in its `preferred form and what I deem to be the best mode of applying the principles thereof; but it is to be understood that, within the scope of the appended claims, I 'contemplate changes in form, proportions and materials, the transposition of parts, and the substitution ofv equivalent members, without departing from the spirit of my invention.

Fig. l is an elevation of one of the pulley-supporting arms, theview being indicated by the arrow 4 in Fig, 1. Fig. 5 is ISpecification of Letters Patent. Ptnted 'Aug27,1918;

Similar reference characters I `use two L-shaped bracket arms each comprising a vertical leg Zand a horizontal leg 3, and the vertical leg being bent to form a diagonal brace 4. The two bracketmem-Yr bers areheld in rigid spaced relationrby means of braces 5 `extending between the vertical legs. AlsoI use two other L-shaped brackets .each comprising a vertical leg 6 and a horizontal leg 7;'and these are preferably made of angle-bars as indicatedin order the better tol withstand the strains jencouiitered. In each of the horizontal legs of the lasts-named brackets are two'slots 8,3, and through each slot extends` a boltA 9, which also vextends through a holey in ,the horizontal portion of the first-named Fig.l 3, the

bracket, as shown in Figs. 1 and 5 most clearly. By means of the bolts, the legs are held in parallel relation respectively; and it is designed that the upper end of the silo wall shall be clamped between the legs 2', 2

(on the outside) and the legs 6, 6 (on the inside). By loosening the bolts, the vertical legs may be spreadfarther apart from each;

other, so that, withinthe range permitted by the length oftherslots 8, 8, the device may be adjusted to llit any `thickness of silo .n

wall. The outer ends of the horizontalnlegs 7 7, extend preferabl'ybeyond the outer ends of the legs 3, 3, and in one of them is a hole 10 and in the other a slotY 11.. Y The'hole is engaged by the eyelet 12 formed in the end of the axle 13 whose free end isadapted to fit intothe slot 11, said axle kbeing thus free to be swung across and supported horizontally on the arms or to be thrown back out of the way so as to leave the space clear between the arms or to be lifted forv the purpose of passing a rope over the spool-shaped pulley 14 carried thereon.

Secured to the vertical legs of the second-A named L-shaped brackets are a pair of sleeves or sockets 15, 15 in which are set the lower ends of the rods 16, 16, respectively, said rods being extended out over the interior of the silo as shown and carrying at their ends another spool-shaped pulley 17, and said rods being also spaced apart in the same manner as the horizontal outi wardly projecting legs yhereinbeore def scribed. 'Ihe pulley ismounted on a suitable axle 18 extending between the two rod ends. The rods may be ladjusted vertically in their sockets and arev held securely in adjusted position by means of the set j by any suitable power, theconveyer is lifted into place, its yupper end passing either insidek or outside the pulley, and its lower end being properly supported when the con-k veyer isfully extended. If the upper end comes up outside the pulley, it is an easy matter, wheny the lower end is supported, to throw back the pulley and bring the conveyer tube in between the arms, with the deflector V22' and the hopper joint 23 extending inwardly `between the rods y16, 16; and, whenever desired, thepipe may be securely lashed to the parts by means of rope. The distributer pipe sections 25 may then be lifted into place to connect with the hopper joint 23 by means of the rope 24 passing over the pulley 17.

rVhere the thickness of the wall is known, the adjustment of the device thereto may be made on the ground before the device is carried to the top, thereby avoiding the necessity fof the somewhat dangerous ex pedient of doing the adjusting in a precarious position on top of the silo wall; The devicebeing light, can be easily carried to the' top by one man who can also slip it over the top of the wall and who can pass a cordl over thepulley .to draw up the strongerV rope by which the lifting of the conveyer is done. Also, the one man can 'f guide the upper end of the conveyer into place and throw the pulley off or on, as may be required, and can attend to the lashing, etc. l Heretofore, thishas been done by f means oi' blocks and tackle, which are cumand no convenient means hasbeen devised for attaching'same to the top of the wall.

I usethe'uninclosed spool-shaped pulley in order to facilitatethe handling of the rope at the various stages in erecting, holding, and taking down the'conveyer and parts, and to prevent theswinging of the conveyer7 as by a high wind, from throwing the rope oli' of the pulley. v l

Having thus described my invention, what I claiml as new is Y 1. The combination of a pair of L-shaped brackets each comprising a horizontal leg and a vertical leg and the vertical leg being upturned to form a diagonal brace, crossbraces rigidly securing said brackets together in spaced relation, a second pair of similarly formed brackets formed with slots in their horizontal legs, bolts extending through said slots and into Vthe horizontal legs of the first-named brackets, the vertical legs being in spaced parallel relation and adapted to bear against the outer and inner face of a wall, and axle hinged to the free end of one of the horizontal legs of the second-named pair of brackets and supported on the free end of the other bracket of said pair and a spool-shaped pulley mounted on said axle.

2. The combination of a pair of parallel 1 to be adapted to embrace opposite sides of a wall, bolt-and-slot connections for adjust-y ably securing the horizontal legs together,

and a pulley and axle hinged to theouter Y end of one of said horizontal legs and laid acrossrthe space between said spaced legs and supported on the opposite leg.

3. The combination 4of a frame formed with outwardly projecting spaced pulleysupporting arms and'formed to it against the outer face of a wall, aV pair of brackets formed to iit against the inner face of theK wall and adjustably securedvto said frame and formed with vertical sockets, a pulley removably supported on the outer ends ofy LESTER E. OHMART.
